The Bill & Melinda Gates Foundation has announced a second round of Reinvent the Toilet Challenge grants totaling nearly US$ 3.4 million. The announcement took place on 14 August during the Reinvent the Toilet Fair in Seattle, USA (see also the earlier post Winners of the Reinvent the Toilet Challenge).

Winning grants:

Cranfield University This nearly US$ 810,000 grant will help develop a prototype toilet that removes water from human waste and vaporizes it using a hand-operated vacuum pump and a unique membrane system. The remaining solids are turned into fuel that can also be used as fertilizer. The water vapor is condensed and can be used for washing, or irrigation. Read Cranfield University’s press release.
